Conclusion
Using various remote sensing methods with open-source and SAR images, the transboundary river has been successfully monitored. Open-source images can be an essential and cost-effective method of supplementing data for investigating inaccessible regions, such as the Imjin River in North Korea. Moreover, intra-variability of water resources of the Imjin River was investigated using Sentinel-1A and
